To all whoinit may concern:

pipe intersected by a pipe and steam from the Be it known that I, HENRY Oo'rrao'vlon, a citizen of the United States, residing at Hinckle'y, in the county of Pine and State oi Minnesota, have invented certain new and useful Improvements in VVood-Distilling A paratus, of which the followingis a speci cation. This ihvention relates to an apparatus for distilling wood and extracting tar, and per'- tains especially to an apparatus for removing gas or steam from the tar, and for facilitating condensation of such gas and steam. I Y The invention is shown in connection with my Patents No. 814,901 and .No. 840,753,

and While designed as an improvement thereupon, such improvement is independent of the particular inventi'm covered by said patents; and it contemplates the provision of asimple and inexpensive apparatus, economical and certain in its-operatioiFof con-. suming tar-producing wood, and of producing pure unadulterated tar containing all the tar roducts of the consumed wood.

T enbject of the invention is to rovide a special form of condenser to whic is connected a pipe for carrying into the condenser gas and steam from the tar during or after its passage from a retort, furnace or still.

- A'further object'of the invention is to provide a wood-still, havin a tar-conveying %or carrying oil gas tar during its passage through said tar pipe.

It is well known that there is a certain amount of gas and steam formed or precipitated during'the rocess of extractin tar from wood by dist: lation, and that suc gas and steam upon condensation mix with the tar thereby injuring the latter, reducing its usefulness, and rendering it entirely useless.

for certain purposes.

Therefore, it is the purdose of thisinven-f tion to overcome and avoir these and various other objections and disadvantages, and to furnish an a paratus wherein and whereby the'tar prod and purified.

Several retorts maybe connected and o 'erated together, but the two shown'in t 'e drawin s will exemplify the invention. .The retorts, 0th being of the same construction only one will be hereinafter described ill-d6.- ta I 2, andis supported by a chambered bottom 3 havin a central tar discharge 4; towhich is 'attac ed a ipe 5.for conveying tar from the retort. ater induction and discharge pipes. 6 and 7 respectively are connected to The heavier of such elements areliquefiedin on into a condenser 9 (hereinafter particu larly described) through a-gooseneck 10 extending from the top of the condenser.

A vapor, steam or ga's pipelfl'connects the tar pipes 5 of each retortwith a condenser '9. (which is a duplicate of the tWOfiOlldBDS-a ers 9) by'means of vertically disposed trap pipes 11, for the purpose of carrying into one and the-same condenserg", vapor, steam and gas from the tar during its passagethrough the tar pipes 5 from the retorts. The vipe -10 is thus made common to bother a retorts, and as the trap'pipes 11- intersect-the pipesfi near the exit of the latter from the retorts,thevapor,gasandsteamarepermittcd to continue with the tar during its assage At the intersection of the pipe 10.and the pipes 11, is a slide-valve 13, by which com 'municationis opened and closed between the pipc ll) and the pipes 11. Thetvro condensers 9 and the condenser 9 being of the-sameconstruction, only one of them will be hereinafter described in dehaving a closed dome 15, a closed bottom 16, and an outlet 17 an annular trough 18 at the bottom of the shell, and providedlwith an outlet 19, a top trough 20 having apertures 21, and one or more intermediate per-s forated troughs .22 a vertical shaft or stem 23 is mounted centrally withinthe' shell and has secured thereto a series of perforated {vconical shelves or hoods 24, which arc preferably of smaller diameter than the shell so same parts throughout the several views-of.

as to; leave an interval orsp'a'ce between the periphery of the hoods and the inner wall of the shell. Water or other cooling fluid being directed upon the shell dome runs into the top trough whence it descends therethrough' against the exterior of the shellfto and through the intermediate trough in contact with the shell to the bottom trough. By-

"products of resinous wood carried into the condenser fall from one to the other of the hoods and duringthe water cooling of the shell are thereby condensed; so that a certain amount of turpentine is precipitated to tl1o-hott0m of theshell whence it is carried' ofi' by an outlet 17. The trap pipe 11 and the (pipe 10 removefrom the tar pipe 5 such pro uctsof the Wood as may follow with the tar into the pipe 5, so that the tar is delivered pipe whereby a tion of a plurality of reto'rts, a filtering condenser for each ietort and connected with; the .body of the'retorts, a filtering condenser common to all the retorts, a vap ror gas a pipe upon theloutsidie of the retorts and discharging into the said common condenser, a tar r I pipe for each retort and extending from the ottom thereof perpendicular to the vapor or gas'pipe, a trap pipe for each retort and connectlng the tar pipes 'with the vapor or gas the retorts areconnected with the'common condenser, and 'a cut-ofit' valve at the intersection" of the vapor pipe and the tar pipesto open and close com munication between the vapor pipe and v the tarpipes for the purpose of operating one or more of the retorts; substantially as shown and described. a
